BACKGROUND 1. Field

The disclosure relates to methods and apparatuses for handling overheatof an electronic device.

2. Description of Related Art

In order to meet the demand for wireless data traffic soaring since thefourth generation (4G) communication system came to the market, thereare ongoing efforts to develop enhanced fifth generation (5G)communication systems or pre-5G communication systems. To achieve a highdata rate, 5G communication systems are considering implementation inmmWave bands other than high-frequency bands adopted for 3G andlong-term evolution (LTE) systems. To mitigate pathloss on 5Gcommunication systems and increase the reach of radio waves, thefollowing techniques are taken into account for the 5G communicationsystem, beamforming, massive multi-input multi-output (MIMO),full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, andlarge-scale antenna technology. Also being developed are varioustechnologies to allow the 5G communication system an enhanced network,such as evolved or advanced small cell, cloud radio access network(cloud RAN), ultra-dense network, device-to-device (D2D) communication,wireless backhaul, moving network, cooperative communication,coordinated multi-point (CoMP), and interference cancellation. There arealso other various schemes under development for the 5G systemincluding, e.g., hybrid frequency-shift keying (FSK) and quadratureamplitude modulation (QAM) modulation (FQAM) and sliding windowsuperposition coding (SWSC), which are advanced coding modulation (ACM)schemes, and filter bank multi-carrier (FBMC), non-orthogonal multipleaccess (NOMA) and sparse code multiple access (SCMA), which are advancedaccess schemes.

Various ongoing attempts are being made to apply 5G communicationsystems to Internet-of-Things (IoT) networks. For example, the sensornetwork, machine-to-machine (M2M), machine type communication (MTC), orother 5G techniques are implemented by schemes, such as beamforming,multi-input multi-output (MIMO), and array antenna schemes.

Overheat attributed to use of mmWave bands may be more likely in 5Gcommunication electronic devices than in pre-5G communication electronicdevices. Thus, a need may arise for technology capable of controllingoverheat in electronic devices for seamless communication.

The above information is presented as background information only toassist with an understanding of the disclosure. No determination hasbeen made, and no assertion is made, as to whether any of the abovemight be applicable as prior art with regard to the disclosure.

Upon receipt, the plurality of phase shifters 238 may changethe phase of the 5G Above6 RF signal received from the outside to thesame or substantially the same phase via their respective correspondingantenna elements. This enables transmission or reception via beamformingbetween the electronic device 100 and the outside.

According to an embodiment, upon receiving the first message (UEassistance information) from the electronic device 100, the base station10 may determine whether to accept or disregard the request from theelectronic device 100 corresponding to the overheat assistanceinformation (OverheatingAssistance) in the first message (UE assistanceinformation).

According to an embodiment, upon accepting the request from theelectronic device 100 corresponding to the overheat assistanceinformation (OverheatingAssistance), the base station 10 may reset theresources for the electronic device 100 based on the resourcecorresponding to the overheat assistance information(OverheatingAssistance).

For example, the overheat assistance information (OverheatingAssistance)may include the information for the reduced maximum bandwidth(reducedMaxBW-FR1) of the first frequency range (FR1) or the informationfor the reduced maximum bandwidth (reducedMaxBW-FR2) of the secondfrequency range (FR2). Upon accepting the request from the electronicdevice 100, the base station 10 may determine to reallocate thefrequency resource corresponding to the information about the reducedmaximum bandwidth (reducedMaxBW-FR1) of the first frequency range (FR1)or the information about the reduced maximum bandwidth(reducedMaxBW-FR2) of the second frequency range (FR2) as the resourceallocated to the electronic device 100.

FIG. 16B illustrates a configuration of the second antenna module 1680included in the electronic device 100.

Referring to FIG. 16B, a second temperature sensor 1681 may be placed toidentify whether the second antenna module 1680 is overheated. Accordingto an embodiment, the second antenna module 1680 may be disposed apredetermined interval apart from the main PCB 1610. For example, thesecond temperature sensor 1681 may be disposed on the module PCB of thesecond antenna module 1680 and may measure the temperature of the secondantenna module 1680 at each designated period or continuously, therebyidentifying the degree of heating.

According to an embodiment, the second antenna module 1680 includingboth the dipole antenna array and the patch antenna array may includethe module PCB which is relatively large in area as compared with theother antenna modules. Thus, the module PCB of the second antenna module1680 may have a space for packing the second temperature sensor 1681.According to an embodiment, the temperature information for the secondantenna module 1680 measured by the second temperature sensor 1681 maybe transferred to the CP or AP, and the CP or AP may determine whetherthe second antenna module 1680 is overheated based on the temperatureinformation for the second antenna module 1680 obtained from the secondtemperature sensor 1681.

FIG. 16C illustrates a configuration of the third antenna module 1690included in the electronic device 100.

The third antenna module 1690 may include a module PCB, an mmWavetransceiver, a PMIC, or an antenna array. For example, an mmWavetransceiver or PMIC may be disposed on a first surface of the module PCBof the third antenna module 1690, and an antenna array may be disposedon a second surface which is different from the first surface. Forexample, the antenna array may include a patch antenna array and emitsignals in a fourth side direction (e.g., a left side direction of theelectronic device 100) of the electronic device 100.

Referring to FIG. 16C, a third temperature sensor 1691 may be placed toidentify whether the third antenna module 1690 is overheated. Accordingto an embodiment, since the third antenna module 1690 is disposedadjacent to the battery 1660 placed on the bottom of the main PCB 1610,the third antenna module 1690 may be sufficiently spaced apart from themain PCB 1610. According to an embodiment, the third antenna module 1690includes the patch antenna array alone and the module PCB therefor maybe small in area.

According to an embodiment, given the limited module PCB area of thethird antenna module 1690 and measurement accuracy of the thirdtemperature sensor 1691, the third temperature sensor 1691 may bedisposed on the FPCB 1650 in a position adjacent to the third antennamodule 1690 and may measure the temperature of the third antenna module1690 as per predetermined periods or continuously, thereby identifyingthe degree of heating.

According to an embodiment, the third temperature sensor 1691 may beconnected with the CP or AP to transfer the temperature informationmeasured for the third antenna module 1690 to the CP or AP. A referencefor determining the degree of heating for the antenna modules may be setto differ per antenna module. Although the temperature informationmeasured by the temperature sensor disposed corresponding to eachantenna module inside the electronic device 100 may be proportional tothe surface heating state of each antenna module, a different referencefor determining heating information may be set per module because theamount of heat transferred to the outside of the antenna module may bevaried depending on the packing structure or heat-radiating structure ofeach antenna module. For example, if the overheat temperature of thefirst antenna module 1670 measured by the first temperature sensor 1671is not less than 70° C. which is set as the overheat referencetemperature for the first antenna module, the first antenna module 1670may be determined to be in the overheated state. When the first antennamodule 1670 is identified to be overheated, the electronic device 100may perform communication using the second antenna module 1680 or thethird antenna module 1690 instead of the first antenna module 1670.

According to an embodiment, while communication is performed using thesecond antenna module 1680 or the third antenna module 1690, thecommunication operation of the first antenna module 1670 may be stoppedto reduce heat in the first antenna module 1670. For example, if thetemperature of the first antenna module 1670 is not less than 60° C.which is set as a candidate beam measurement reference temperature forthe first antenna module 1670, it may be excluded from the candidatebeam list or neighbor beam list for a designated time. For example,after the designated time elapses and if the first antenna module 1670is cooled down to 60° C. or less, it may be added back in the candidatebeam list or neighbor beam list.

According to an embodiment, the overheat reference temperature andcandidate beam measurement reference temperature for the second antennamodule 1680 or the third antenna module 1690 may be set to differ fromthose of the first antenna module 1670 and may be used as heating statedetermination references when the second antenna module 1680 or thethird antenna module 1690 operates.

The overheat reference temperature and candidate beam measurementreference temperature for each antenna module may be set as a hysteresiscondition for each antenna module, preventing a state variation indetermination of heating. The per-module heating informationdetermination references are provided merely as an example and are notlimited by any one embodiment but may rather be set to various valuesconsidering the placement of the temperature sensor corresponding toeach antenna module.
